How does it not work when using sdpdemux? Are packets getting lost, or
what exactly is the reason for the frame drops?

Also note that sdpdemux is using an rtpbin, which especially includes
an rtpjitterbuffer element. Does your manual pipeline fail in similar
ways if you add an rtpjitterbuffer before the depayloader?
